Dr Rhea Longley, Lab Head | WEHI Researcher Profile

Q: Serological markers of recent exposure to malaria

We are developing serological markers of recent exposure to malaria infections to aid elimination of this disease. We are doing so via the measurement of antibody responses in samples from cohort studies conducted in various malaria endemic regions around the world, along with the development of specialised diagnostic algorithms. This work is currently funded by: NHMRC Development Grant, Ramaciotti Health Investment Grant, eAsia Joint Research Program Grant and a NHMRC Emerging Leader Fellowship to Dr Longley.

Q: Identification of novel malaria vaccine candidates

We are utilising well-characterised epidemiological studies to support the discovery and validation of novel malaria vaccine candidates. People in malaria-endemic countries naturally gain immunity to clinical disease. We are investigating which proteins are good targets for a vaccine-induced protective immune response and how antibodies against these targets induce protection against clinical disease. Our recent studies focus on measurement of functional antibody responses and have been funded by an Australian Centre of Research Excellence in Malaria Elimination Seed Grant.

About

I am broadly trained in parasitology, immunology and epidemiology, with over 16 years of experience in malaria research conducted in Australia, the UK (Oxford University, as a Rhodes Scholar) and Thailand. I am an early career researcher, 7 years post-PhD FTE, and am leading the serology program of work within the Mueller Lab at WEHI. In 2025, I am starting my own lab at WEHI, funded by a Viertel Senior Medical Research Fellowship. I hold at Adjunct Professorship at Mahidol University, Thailand.

My research is focused on the immunological response to Plasmodium infections. Specifically, I am currently looking at the antibody response to Plasmodium vivax infections in human populations. I am passionate about translational research and am contributing to commercial development of a RAT-style diagnostic for malaria and clinical trials in numerous malaria-endemic regions to generate the evidence base required.

I am invested in mentoring the next generation of scientists, with a focus on diversity and inclusion as evidenced by multiple extra-curricular roles and leadership positions on committees aiming to address inequality.
